Abstract:

The oil and natural gas resources are rich in the hinterland of the Taklamakan desert, where weather is extremely dry, ecological environment is extremely frail. In this study,in order to provide dependable foundation for the reasonable exploitation of groundwater, the protection and improvement of water quality. A section crossing the from Kunlun piedmont to the hinterland of Taklimakan Desert is monitored,Piper diagram is utilized to analyze the hydrochemical type, and NETPATH Modeling is used to simulate the process of chemical evolution of groundwater. The results obtained are stated as follows: (1) The groundwater hydrochemical types are comparatively single in the area, the main types are Na-Mg-Cl-SO4 and Na-Cl-SO4; (2) The main representation properties of the water chemical evolution model are the strong evaporation and concentration, the dissolution of mirabilite, rock salt and pyroxene, and the more prominent Ca2+/Na+ ion exchange.

Key words: groundwater, chemical evolution, NETPATH model, Taklimakan Desert
